With a reproduction-only disc having a large recording capacity, an interactive function having a higher degree of freedom than the related art can be easily accomplished. A virtual player model corresponding to a function of a player is created and described in Java. BDBasicPlayer 210 detects a user input and the status change of the player and generates an event. An object 211 that implements a listener interface registers an event listener corresponding to an event that the object 211 is caused to receive to BDBasicPlayer 210 before the event takes place. When the event becomes unnecessary, it is unregistered. BDBasicPlayer 210 transmits the event to the object 211 in which the event listener has been registered. The object 211 executes a method corresponding to the received event. The relationships between events and methods can be flexibly set. Thus, a complicated interactive function can be easily accomplished.

A content signal having a control signal added thereto indicating whether or not a playback restricting function for restricting reproduction is activated is recorded on a disk. When an encryption key generation section determines at the time of reproduction that the content signal has the control signal added thereto indicating that the playback restricting function is activated, it is determined whether or not a playback permission condition is satisfied. The playback permission condition is read from the disk, or acquired via a communication section if it is not stored on the disk. A correct encryption key Kp is supplied to an encryption processing section only when the playback permission condition is satisfied. The encryption processing section decrypts the encrypted content signal recorded on the disk with the encryption key Kp and the correctly decrypted content signal is outputted from an output control section.

A GUID as title information and a global serial number are recorded in a BCA of a digital video disc 60. A hash value of the GUID is embedded as an electronic watermark in a data area 64. When content data is reproduced from the digital video disc 60, a match of information of the two GUIDs is checked so as to prevent the digital video disc 60 from being illegally copied. A lead-in area 63 and a managing organization 20 provide disc revocation lists. With a global serial number and a disc revocation list, content data can be prevented from being reproduced from an illegally distributed disc. A film WM detector 84 detects data embedded in a movie shown in a theater so as to prevent content data from being reproduced from a disc on which the embedded data is recorded. Thus, content data can be prevented from being reproduced from an illegally distributed disc before a copyright supervisor of the content authorizes the disc to be distributed.

In order to play waveform data back at a variable performance tempo by using waveform data which complies with a desired reference tempo, the present invention performs a timeline-expansion/contraction control on the waveform data to be played back, according to the relationship between the performance tempo and the reference tempo. The present invention also determines whether to limit the playback of the waveform data according to the relationship between the performance tempo and the reference tempo. In the case that playback is to be limited, the present invention stops playback of the waveform data, or reduces the resolution of playback processing and continues playback of the waveform data. The present invention stops playback of the waveform data when, for example, the relationship between the performance tempo and the reference tempo is a relationship in which the waveform data would be played back at a performance tempo which would cause a processing delay or a deterioration of sound quality. As a result, it is possible to preemptively prevent a system freeze and solve problems such as the generation of music which has a slower tempo than the desired performance tempo, or the generation of music which includes the intermittent cutting out of sound due to noise, or a significant reduction to sound quality.

The present invention relates to an apparatus and a method for protecting the copyright of an information signal recorded on a recording medium such as a DVD (Digital Video Disc) for presenting the signal to the user or an information signal transmitted through transmission media such as the Internet and for preventing an illegal copy of such an information signal. To put it in detail, information on copyright protection which is read out from the recording medium and information on copyright protection which is encrypted to make the information difficult to alter is used. If both of the information do not match each other, the information on copyright protection is judged to have been altered in an attempt to play back the information signal which is obtained as a result of an illegal copy operation in which case, the operation to play back the information signal is disabled.
